I didn't say that VM was slower in any universal sense.  It does slow 
certain things down at certain times, though (for example, while it's 
swapping).

Doesn't really depend, no.  MacOS is somewhat OO; it has some of the 
features.  No definition will allow it to be called "very" OO, though.  
Perhaps even some of the true OO OSes couldn't be called very OO!  I 
wouldn't be able to guess on that; all I know is Geos, and it looks very 
OO to me (I develop for it).

What OSes are acknowledged as full OO?  I know about NextStep and Geos.  Any 
others?
